Physics 1 Chapter 2: Motion Along a straight line

Displacement is defined as:

A change from position x(1) to position x(2)

What is the formula for displacement?

Delta x = x(2) - x(1)

1st restriction on general properties of motion:

Straight Line- Motion:

The motion is along a straight line only. The line may be vertical, horizontal, or slanted, but it must be straight

2nd restriction on general properties of motion:

Focus on Motion Changes:

Looking at how the object’s speed and direction change over time. If it speeds up, slows down, stops, or changes direction (without discussing the force causing these changes)

3rd restriction on general properties of motions

Particle like behavior:

Object is threated as either a point like particle or as a solid object that moves uniformly (every portion moves in the same direction and at the same rate) rather than something that tumbles or rotates

Word Formula for Average Velocity

Displacement/time

Average Velocity

(x₂-x₁)/(t₂-t₁)

Word formula for Average speed

Total Distance/ Total time

What is the total amount traveled?

Find total distance

Word Formula for Time

Distance / Speed

What is the average value for the entire trip?

Find average speed
